Does this look like correct gas pedal assembly?
And I’ll add, if you’re going to use that later style swing pedal and weld a spoon onto the end, it will still not work with your early pedal. The slant 6 pedal has a trough on the back to accommodate the roller mechanism from the slant linkage setup. Only the V8 pedal has the flat plastic rub pad on the rear for the spoon to rub on
